The Fusheng A series air-cooling reciprocating air compressor is designed for general industry use. Its standard operating pressure falls between 7 and 12 kg/cm2G and is suited for applications requiring variable high efficiency piston displacement volumes. The A series compressor runs from 0.37kW (½hp) to 15kW (20hp) and is designed for heavy-duty applications, low speed operation, and prolonged use. It is equipped with a fully-automatic and semi-automatic control for greater energy efficiency during loading/unloading or shut-down. It is suitable for use in industries involving automobile maintenance, paint and sprays, materials production, textile, and tires. The Fusheng A series air compressor has a wide scope of applications and can be customized into a 2-stage or 3-stage compression with operating pressures ranging from 18 kg/cm2G to 35 kg/cm2G. The suction/discharge valves are made of a special Swedish steel that carries essential properties such as impact resistance and a high tolerance for high-temperature operations. The cylinders, connecting rods, and piston rings are produced and ground by precision machines, allowing the A series compressor to offer excellent airtightness and low friction. All these features, including a high-precision crankshaft and crankcase, allow for balanced compressor operations with low vibration and high output volume.
The Fusheng A series is verified by TUV Rheinland, a third-party testing laboratory. The design of the compressed air system is based on the five elements (the 5 S’s) that we want our products to provide for the customers - security protection (Safety), ease of Service (Service), stability and reliability (Stable), the international certification (Specification - compliant) and Energy Saving (Cost Saving).
Heavy-duty, Low Speed
Single-stage air-cooled air compressor
The single-stage air compressor operates at the pressure range between 0-7 kg/cm2G. It produces more compressed air per horsepower than a two-stage compressor. However, if the operating pressure goes beyond 7kg/cm2G, a two-stage air compressor produces more compressed air for every horsepower. Therefore, a two-stage air compressor is recommended for operating pressure more than 8 kg/cm2G.
Two-stage air cooled air compressor
The two-stage air compressor operates at the pressure range between 8-35 kg/cm2G. The compressed air is subject to have proper cooling and compression ratio as it exits from first stage compression and enters into second stage compression. Therefore, the efficiency is better than single-stage compressor, thus more power saving.
① Cooling copper tubing - Equipped with highly efficient heat dissipating fins, the copper tubing allows the heat generated to dissipate effectively, thus improving the air compression efficiency.
② Inlet and outlet valves - Equipped with highly efficient heat dissipating fins, the copper tubing allows the heat generated to dissipate effectively, thus improving the air compression efficiency.
③ Cylinder head - The concentrated, streamlined air flow allows for efficient heat dissipation.
④ Cylinder - The inner diameter is machined and milled using CNC techniques, giving the cylinder good wearing resistance and durability.
⑤ Crankshaft - Forged with high-quality steel, the crankshaft features high strength. The wearing parts are surface-toughened for extremely high wearing resistance. A counterweight minimizes vibrations.
⑥ Piston ring - The compression ring and oil ring are precision-machined to minimum lubricant consumption. This feature keeps the valve from carbon deposit or being burned for loss of lubricant.
⑦ Connecting rod - The links are precision-machined. The boring and alignment are kept within the ideal design requirements, allowing the compressor to run more smoothly and effortlessly.
⑧ Bearing - High-quality imported bearings are used for linger service life.
⑨ Air filter - The filter cleans the air sucked in while serving as a muffler to remove excessive noises.
⑩ Automatic unloading device - The filter cleans the air sucked in while serving as a muffler to remove excessive noises.
⑪ Belt-driven pulley for the compressor - The pulley is carefully balanced and calibrated for stable operations of the compressor.
⑫ Crankcase - The center hole and surfaces of the bearing are machined in one run by a single CNC workstation, ensuring the alignment and verticality.
Air Compressor Choice of Models
Determine operating pressure, kg/cm2G2G
The discharge pressure of an air compressor is based on the actual pressure, the pressure drop that comes from air supply piping and purification system need to be considered.
Determine air demand, l/min
Operating cycle, maximum peak air demand, air storage, possible leaks and future expansion shall be considered when determining the actual air demands. In general, extra 20% is considered in addition to the actual air demands.
Choose the right model
As the two factors above are determined, then can choose the right model from this catalogue. (Special care is advised as the choice should be made based on the "actual displacement" under the operating pressure.) In general, the actual displacement is single stage x 0.65 or two stage x 0.8. Please refer to the specifications of respective models.
Choose the motor
Based on the air compressor model selected and the conditions of environment in operation; for example, 110V single phase, or 220V or 380V 3-phase.
Others
It is recommended to use a 3-phase motor for Fusheng's air-cooled compressor of 2HP or more. When a 3-phase motor is used, it is recommended to install an electromagnetic switch for a fully automatic model, or there is a risk of motor damage.

Choose the appropriate way of operating based on it is used.
Semi-automatic
Fully automatic
Semi-automatic model:
For a semi-automatic model, a pilot valve is used to control the unload and load conditions of the compressor. When the system pressure reaches the upper pressure limit defined (7.0kg/cm2G for example), the pilot valve opens and drives the suction unloader, thus allowing the compressor to run unloading. When the system pressure drops below the lower pressure limit defined (6.0 kg/cm2G for example). the pilot valve closes to allow the compressor to run loading. The semi-automatic model is suitable for where the compressed air is used frequently.
Fully automatic model:
The fully automatic model controls the unload and load conditions of the compressor using a pressure switch. When the system pressure reaches the upper pressure limit defined (7.0kg/cm2G for example), the pressure switch on to cut the motor's power off, and therefore the motor stops. When the system pressure drops below the lower pressure limit defined (5.0 kg/cm2G for example), the pressure switch turns the motor's power back on, thus, the compressor start running again. The fully automatic model is suitable for intermittent operations. For the protection of motor and electromagnetic switch, the compressor should not be turn on and off more than 6 times per hour.2G)時，壓力開關動作，即自動切斷馬達的電源，使空壓機停止運轉。當系統壓力降至設定的下限(5.0 kg/cm2G)時，壓力開關又自動接通電源，使馬達重新啟動，空壓機恢復運轉。全自動操作方式，適用於間歇性的工作。為保護馬達及電磁開關，空壓機的啟動次數，不宜超過每小時六次。
